The invention provides a flap type water flow force device, which is arranged in water, the lower side is a water filling area, the upper side is an inflated area, and the water filling area and the inflated area are two A space that is independent and isolated. The upper part of the cylinder forms the air between the two sides, so that the water is not reversed due to the direction of the water flow. The upper part of the cylinder is connected to the air pipe to open the water surface, so that a certain air pressure is maintained in the gas-filled area to avoid the gas-filled area. In the problem of forming a vacuum, the lower half of the cylinder forms a flow between the water, so that the vane is continuously rotated by the flow of water, thereby driving the axle to rotate, and the rotating axle can continuously output power.

As shown in Fig. 1, Fig. 2 and Fig. 11, the flap type water flow device of the present invention specifically includes: a cylinder 1, an axle 2, a plurality of buckets 3, and a bucket moving machine control assembly. The axle 2 is bored in the cylinder 1, and the axis of the axle 2 coincides with the axis of the cylinder 1. The vane 3 is hinged on the axle 2 in the axial direction of the axle 2, and the plurality of vanes 3 are radially arranged, and the outer edge of the vane 3 is as close as possible to the inner wall surface of the cylinder 1 so that the vane 3 has a water flow force The largest area. The vanes 3 can only move within a certain angular range of the radial direction of their radial position (i.e., clockwise in Fig. 1). The vane moving machine control assembly is used to independently control each vane 3 to be fixed or disengaged from its radial position.

As shown in FIG. 4 to FIG. 7 , as a preferred embodiment of the present embodiment, the flap type water flow force device of the present invention further includes two first leakage preventing strips 14, a second leakage preventing strip 15 and a third leakage preventing strip. The strip 16 and the two end plates 12, both end plates 12 are circular, and are respectively disposed at both ends of the vane 3 (i.e., at the radial edge of the vane 3), the axis of the end plate 12 and the cylinder 1 The axis of the end plate 12 is overlapped, and the end plate 12 defines a shaft hole 18. The two ends of the wheel shaft 2 respectively pass through the shaft hole 18 of the end plate 12 to fix the end plate 12 and the axle 2 together, and the end plate 12 is closely attached to the vane 3. Radial end edge. As shown in FIG. 7 to FIG. 9, the inner wall of the end cover 17 at both ends of the cylinder 1 is provided with a first leakage preventing strip 14 at a position along the horizontal plane 6, and the inner wall of the cylinder 1 at the position of the water inlet 6 at the side edge of the water inlet 4 is provided with a cross section. An arc-shaped second leakage preventing strip 15, a second leakage preventing strip 15 is disposed along the longitudinal direction of the cylinder 1, and the width of the second leakage preventing strip 15 is such that the radial position of the two adjacent vanes 3 corresponds to the cylinder 1 The distance on the inner wall. As shown in FIGS. 7 and 10, the third leakage preventing strip 16 is disposed on the side of the dam 10 that blocks the vane 3. The purpose of providing the first leak preventing strip 14, the second leak preventing strip 15 and the third leak preventing strip 16 is to prevent water from leaking into the inflated area 8. As shown in FIG. 8 and FIG. 9, the two ends of the cylinder 1 are sealed, that is, the cylinder 1 has two end caps 17, and the two end caps 17 may be integrally formed with the side wall of the cylinder 1, or may be Additional settings. In the state of use, the cylinder 1 is placed horizontally according to its axial direction. An air hole (not shown) is opened in an upper portion of the cylinder 1, that is, a side above the horizontal plane, and the air hole is connected to the air pipe (not shown) to open the water surface, so that a certain air pressure is maintained in the gas-filled region 8. . The air holes may be opened in one or more according to actual needs, and the shape of the air holes is not limited, and may be circular or elongated, and may be along the length of the cylinder 1 when it is elongated. Directions are opened. The cylinder 1 is provided with a water inlet 4 and a water outlet 5 along its axial direction. The water inlet 4 and the water outlet 5 are located at a horizontal plane 6 passing through the axis of the cylinder (the horizontal plane 6 is not real, as shown in Figs. 1 and 11). The position indicated by the reference numeral 6 is actually the vane 3, except that the vane 3 is just on the same side of the horizontal plane 6, and the water inlet 4 is located at the end of the cylinder 1 facing the water flow, and the water outlet 5 is located at the circle The barrel 1 faces away from the other end of the water flow. When the cylinder 1 is placed in the water, the horizontal plane 6 can also adjust a suitable inclination angle in accordance with the direction of the water flow due to the action of the water flow. The water inlet 4 and the water outlet 5 are disposed on the cylinder 1 so that water can enter the cylinder 1 and push the bucket 3 to rotate by the water flow force, and can be discharged from the water outlet 5 during the rotation of the bucket 3 The discharge, that is, the water, is continuously supplied from the water inlet 4 into the cylinder 1, and the cylinder 1 is continuously discharged from the water outlet 5.

In addition, in order to allow the vanes 3 to enter the inflated region 8 from the water-filling region 7, the water is not brought into the inflated region 8 to ensure that the flap-type water flow device is rotated forever, as shown in FIG. The side of the nozzle 5 near the horizontal plane 6 has a dam 10 projecting inwardly from the side wall of the cylinder 1. When the vane 3 is rotated to the position of the bar 10, the lower end of the vane 3 overlaps with the upper portion of the baffle 10, and the baffle 10 can restrict the rotation of the vane 3 and the axle 2 synchronously for a certain period of time, and the water can be prevented from being Bringing into the inflated area 8, the length of the baffle 10 protruding from the side wall of the cylinder 1 should not be too long or too short. If it is too long, the vane 3 cannot be crossed, affecting the subsequent rotation, but if it is too short, The bucket 3 is not blocked for the purpose of water isolation. Therefore, the length of the dam 10 is generally designed to block one of the vanes 3 closest to the dam 10 on the side of the spout 5 so that it cannot continue to rotate synchronously with the axle 2 under the action of water flow, and to follow the other When the vane 3 reaches the position of the bar 10, the vane 3 is lifted by the axle 2 to be guided by the bar 10. In addition, the dam 10 can also be used It is set to be laterally movable under mechanical control or tilted to the left and right (Fig. 11) by an angle so that the vane 3 can pass through the dam 10.

In order to continuously output the rotational power of the axle 2, both ends of the axle 2 should extend beyond the ends of the cylinder 1 to be connected to an external device. Further, both end covers of the cylinder 1 can also serve to support the axle 2 at the same time. A shaft hole may be formed in both ends of the cover, and the axle 2 is fitted into the shaft hole of the both end covers by the bearing (since the above structure is a conventional technique, it is not shown in the drawing).

As shown in FIGS. 2 and 11, the vane 3 is hinged to the axle 2 in the axial direction of the axle 2, and the vane 3 and the axle 2 are hingedly connected in order to allow the vane to rotate a certain angle about the axis of the hinge 11. The angular extent of rotation about the axis of the hinge 11 should be the angle between the radial position of the vanes 3 in the reverse rotational direction to the subsequent radial position of one of the vanes. The end plate 12 is provided with a retractable vane movable mechanical control component at each of the radially rotating positions of the vane 3 under the action of the water flow force in the radial position. The vane movable mechanical control component of the embodiment is A plurality of small columns 13, one small column 13 corresponding to one of the vanes 3, to control each of the vanes 3 to be fixed or disengaged from its radial position, and the telescopic movement of each of the vane movable mechanical control components is independent. When the vane 3 is in the inflated region 8 and is returned to the radial position, the corresponding post 13 is in an extended state to block the vane 3 from reversing and fix it at its radial position. . When the vane 3 is in the water filling region 7, the corresponding small column 13 is also in an extended state to block the rotation of the vane 3 and fix it in a radial position where it should be. Only when the vane 3 is rotated to the position of the crosspiece 10 and the front vane 3 has passed the barrier of the crosspiece 10, the corresponding post 13 of the vane 3 is in a contracted state, so that the vane 3 is disengaged from it. Radial position. In the present embodiment, the movable mechanical control assembly is disposed on the end plate 12. Of course, the vane movable mechanical control assembly may not be disposed on the end plate 12, but may be disposed on the vane 3 in other forms as long as the control of the vane 3 can be achieved. Further, the outer wall of the end plate 12 is as close as possible to the inner wall of the end cap of the cylinder 1. The vane 3 is fixed to the radial position of the vane 3 in addition to the rotation of the axle 2 until it approaches the crosspiece 10, and the vane 3 is fixed in the radial position when the vane movable mechanical control unit post 13 is extended. 2 Rotating to the close to the bar 10 and the blocking of the front vane 3 over the bar 10, the bucket movable mechanical control group The small column 13 is retracted to release the freedom of movement of the vanes 3, and the vanes 3 can move around the axis of the hinge 11. The corresponding vane moving mechanical control assembly of the other vanes 3 is arranged in exactly the same manner as the corresponding vane moving mechanical control assembly of the vane 3. Otherwise, the vanes 3 located in the water-filling region 7 do not maintain a certain state under the action of the water flow force of the water, nor do they drive the axle 2 to rotate. As shown in Fig. 2, the vane 3 and the axle 2 in this embodiment are connected by a hinge (i.e., hinge) 11. Moreover, in general, the length of the cylinder 1 is long, and the length of the vane 3 needs to match the length of the cylinder 1, so that one vane 3 usually needs to be connected to the axle 2 by a plurality of hinges 11, and FIG. 2 shows three Wheels 3. The purpose of the plurality of vanes 3 being arranged radially is for the presence of the vanes 3 in the water filled region 7 and the inflated region 8, i.e., there is always water acting on the vanes 3 in order to drive the axle 2 to rotate continuously. The vanes 3 are preferably evenly distributed on the outer circumference of the axle 2 on the premise of being arranged radially.

As shown in Figs. 1 and 11, the number of the vanes 3 is determined in accordance with parameters such as the size of the cylinder 1, the rotational speed of the axle 2, and the like, and the vane 3 in the present embodiment shows twelve. As shown in Fig. 2, it is preferable that the shape of the vane 3 is elongated, so that the vane 3 has a maximum area that is subjected to water flow force, and the axial outer edges of the vane 3 and the axle 2 should be as close as possible to the inner wall of the cylinder 1. . As shown in Fig. 4, the other two opposite sides of the vane 3 should be closely attached to the inner walls of the end plates 12 at both ends.

As a preferred embodiment of the present embodiment, in order to ensure the amount of water inflow and the amount of water to be effectively pushed to rotate the vane 3, the water inlet 4 and the water outlet 5 are both elongated and open from the end close to the cylinder 1 to the vicinity. The other end of the cylinder 1. Moreover, in order to ensure the water inflow effect, the water that has just entered the water filling region 7 can be pushed by the water entering the water inlet 4 to continue to rotate into the water filling region 7, and the water entering from the water inlet 4 is minimized. Partially crossing the horizontal plane 6 so as to prevent the center of gravity of the filled water portion of the cylinder 1 from being shortened from the axle 2, preferably both sides of the water inlet 4 are offset from the horizontal plane 6, or both sides of the water inlet 4 are not at the horizontal plane. 6 on.

The water of the present flap type water flow device itself that leaks slightly into the inflated area 8 or the water that is carried by the vane 3 from the water filling area 7 into the inflated area 8 causes the water of the vane 3 to follow the rotation of the axle 2 Bring back the water filling area 7. In order to enable the vane 3 to move around the axle 2, the vane 3 can be hinged to the axle 2 by means of a hinge in another manner, as shown in Fig. 3, which is provided at the ends of the vane 3 near the axle 2 The protruding boring head 9 and the boring head 9 are inserted into the mortise 19 provided at the corresponding position on the end plate 12, and the boring head 9 functions as a rotating shaft.

As shown in FIG. 12, when the vane 3 is moved to the position of the crosspiece 10, it is separated from the original radiation position by the blocking of the crosspiece 10, so that the vane 3 can be restored to the original position after crossing the crosspiece 10. (ie, the position of the dotted line in FIG. 13), each of the vanes 3 is provided with a return mechanical control assembly (not shown) for maintaining the return of the vane 3 in a radial arrangement, and the return mechanical control assembly is preferably The spring and the spring have the advantages of simple structure, convenient use and good rebound effect. Referring to FIG. 11 or FIG. 12, for example, a blade 3 on the dam 10 may be disposed on the left side or the right side of the blade 3, and should be disposed on the left side. It is a compression spring, and when it is placed on the right side, it is a tension spring. The return mechanical control assembly on the other vanes 3 is arranged in exactly the same form as the return mechanical control assembly on the vane 3.

If the size of the vane 3 is large, the use of a spring will not be sufficient to control the return of the vane 3, and the return of the vane 3 may be in other manners, such as the return mechanical control assembly may be disposed on the end plate 12. Electric motor drive method, etc. Since the flap type water flow device of the present invention is disposed in the water, it is not easy to introduce external electric energy into the device of the present invention. Therefore, when the electric motor drive mode is employed, the end plate 12 must have a built-in power generation system, that is, an end plate. 12 is a hollow structure, and the power generation system is disposed inside the end plate 12. The power generation system will utilize its own kinetic energy. As shown in FIG. 14, the end plate 12 is provided with a suspension generator set driven by a gear, and the suspension generator set is used for power control of the activity of the bucket 3, and continues to be combined with FIG. The suspension generator set includes a suspension rod 20, a power generation gear set and an internal power supply generator 24; the suspension rod 20 is provided with a circular hole (not shown) for passing the axle 2, and the axle 2 is assembled by bearings. In the circular hole of the suspension rod 20; the upper end of the suspension rod 20 is fixed with a gear wheel shaft 21 parallel to the axle 2, the power generation gear set includes an end plate engagement gear 22 and a generator engagement gear 23, the end plate engages the gear 22 and generates electricity. The machine engaging gears 23 are coupled together and are both mounted on the gear wheel shaft 21 by bearings, the diameter of the end plate engaging gear 22 being smaller than the outer edge of the end plate 12 to the outer edge of the axle 2, and the generator engaging gear 23 The diameter of the end plate engaging gear 22 is smaller than the diameter of the end plate engaging gear 22, and the inner wall of the opposite end plate 12 of the end plate engaging gear 22 has an inward tooth 25 which engages with the inward tooth 25 on the inner wall of the end plate 12. Engagement; the internal power generator 24 is fixed to the lower end of the suspension rod 20, and the generator engagement gear 23 passes through a power transmission belt (not shown) and a mechanical power input portion of the internal power supply generator 24 (not shown). Connected to provide power to the internal power generator 24; the lower end of the suspension rod 20 is further provided with a weighting weight (not shown), which is arranged to adjust the weight distribution of the suspension rod 20, so that the suspension rod 20 When the end plate 12 is rotated, the hanging position can be maintained as much as possible.

Under the driving of the vanes 3, the axle 2 will continuously rotate to generate kinetic energy, and the kinetic energy generated by the axle 2 is mostly outputted outward for power generation, and a small portion is used for self-use to generate power for the internal power generator 24. As shown in FIG. 14, the end plate 12 is continuously rotated by the axle 2, and since the end plate engaging gear 22 meshes with the inward gear teeth 25 on the inner wall of the end plate 12, the rotation of the end plate 12 will drive the end. The plate is coupled to the gear 22 for continuous rotation. Since the generator coupling gear 23 is coupled with the end plate coupling gear 22, the end plate coupling gear 22 will drive the generator coupling gear 23 to rotate, and the generator engagement gear 23 will pass the power. A drive belt (not shown) continuously transmits power to the internal power generator 24 to generate electricity. The internal power generator 24 is used to control the bucket 3 return after power generation, and can also be used for the extension and retraction of the small column 13 in the end plate 12.

The working principle and working process of the flap-type water flow device of the present invention are briefly described below with reference to the accompanying drawings:

In use, the flap-type water flow device of the present invention is placed in a river or ocean current, that is, as shown in Figs. 1, 11 to 13, as shown in Fig. 12, and three of the vanes 3 are taken as an example below. To explain, the three vanes are now defined as the vane 3a, the vane 3b and the vane 3c, respectively. When the vane 3a rotates in the counterclockwise direction, the fan-shaped space A enters the position of the water inlet 4, and the flap type water flow The water that flows from the power unit to the water side flows into and fills the entire sector space A due to the flow of water.

Continuing with Fig. 12, at the same time, when all the vanes 3 continue to rotate in the counterclockwise direction, the vanes 3b are blocked by the crosspiece 10, and the vanes 3c are rotated in the normal manner, at which time the radial position of the vanes 3b corresponds. The vane activity mechanical control component column 13 is retracted and returned In the end plate 12, the free movement of the release vane 3b is made to deviate from its radial position, so that the vane 3b can move around the axis of the hinge 11, and the vane 3b is still in close contact with the water pressure in the fan-shaped space B. In the dam 10, the fan-shaped space B between the vane 3b and the vane 3c is continuously narrowed, so that the water in the sector B is squeezed, and the cylinder 1 is discharged from the water outlet 5.

As shown in Fig. 13, when the vane 3c is rotated to the position of the crosspiece 10, it is hindered by the crosspiece 10, and at the same time, since the other vanes 3 are still rotating the axle 2, when the vane 3b is rotated by the axle 2 After driving a certain angle, when the distance from the edge of the vane 3b to the axis of the axle 2 is less than or equal to the distance from the axis of the axle 2 to the crosspiece 10, the vane 3b is disengaged from the baffle 10 and passes over the crosspiece 10 to return around the hinge 11. The axis is freely movable, and the returning mechanical control assembly such as a spring or a motor driving method returns the vane 3b to the original radial position, and is further extended by the vane movable mechanical control post 13 to re-fix the vane 3b. Radial position. Because of the water flow force, the water flow continuously passes through the flap-type water flow force device, and the vane 3 is continuously driven to drive the wheel shaft 2 to rotate, and the flow is continuous.

As can be seen from the above description, the flap type water flow device of the present invention can keep the water filling region 7 (the lower half in Figs. 12 and 13) filled with water and the inflated region 8 (the upper half in Figs. 12 and 13). ) There is always air, so that the axle 2 rotates all the time.

The energy loss of the flap-type water flow device of the present invention is mainly in three parts: 1) the mechanical friction of the rotating shaft 2, and the friction between the two sides and the inner wall of the end plate 12 when the vane 3 moves away from the radial position, first The frictional force generated by the leakage preventing strip 14 in close contact with the outer wall of the end plate 12, the frictional force generated by the second leakage preventing strip 15 in close contact with the axial outer edge of the vane 3, and the third prevention on the vane 3 and the detent 10 The friction generated by the contact of the strip 16; 2) the water in the inflated area 8 is returned to the water-filled area 7 by the vane 3; 3) the vane 3 is returned to the original radial shape after being blocked by the strip 10 The energy required for the location. Therefore, the vane 3 is made of a lightweight material, or the vane 3 is designed to be hollow to reduce the weight of the vane 3, and the loss of energy can be correspondingly reduced.

The above three parts of energy loss are close to fixed. According to reason, under the huge energy force of river or ocean current, the water flows through the flap-type water flow device to drive the energy generated by the rotation of the vane, far exceeding the energy loss, offsetting the energy loss, and A large amount of surplus capacity to drive the generator set to generate electricity. The following is a description of the energy produced by the flap-type water flow device of the present invention by preliminary estimation:

It is assumed that the inner diameter of the cylinder 1 or the radial length of the vane 3 is R, assuming that the length of the cylinder 1 is L and the area of the vane 3 is RL. Assuming that the flow of water through r is t, the flow velocity v = r / t. Water density P = 1000 Kg / m ³ .

Preliminary estimated power P = (l/2)

(l/2) P RLv ³ . Assuming that R is 1 m, the length L of the cylinder 1 is 1000 m, the water flow velocity V is 1 m/sec, and the power P = (1/2) X 1000 X 1 X 1000 X 1 ³ =0. 5 megawatts. The same device, if placed at a water flow velocity V of 3 m / s, the power P = (l / 2) X 1000 X 1 X 1000 X 3 ³ = 13. 5 megawatts.

Comparison of power generation capacity:

The Three Gorges Dam hydropower station installed a total of 32 sets of 700,000 kW hydro-generator units. There are also two 50,000-kilowatt power units with a total installed capacity of 22.5 million kW, or 22,500 MW. The middle reaches of the Yangtze River are one thousand kilometers long, with an average flow rate of 1 m/s. It can be equipped with tens of thousands of leaf-shaped water flow devices with a radius of 1 m and a length of 1000 m in the river. The power generation can exceed the power generation of the Three Gorges Dam hydropower station. the amount. The water flow velocity in the upper reaches of the Yangtze River reaches 3 m / s, and the power generation of the same device is increased by a factor of ten. In fact, the annual average water resources of the Yangtze River Basin is 996 billion cubic meters, and the theoretical water reserves of the whole basin are about 280 million kilowatts. The developable capacity is about 260 million kilowatts, about 11 generations of the Three Gorges Dam hydropower station. Times, if it can achieve half of the effect, it has 5 times the power generation capacity of the Three Gorges Dam hydropower station.

In addition, ocean current energy is even larger, and the theoretical average power of China along the ocean current is 140 million kilowatts. The total flow of the Gulf Stream in the United States has reached 7400 to 93 million cubic meters per second, which is more than 80 times the total amount of all rivers on land. Compared with the rivers in China, it is roughly equivalent to 2,600 times the flow of the Yangtze River or 57,000 times that of the Yellow River. Researchers at the Woods Hole Ocean Research Institute in the United States point out that the Gulf Stream is driven by wind, the Earth's rotation, and the heat that moves toward the North, which is equivalent to 2000 times the energy generated by the United States.

The river currents in the world are rich in energy resources. If the world's river currents are properly set up, the generated leaf-type water flow device of the present invention can generate enough power to replace all existing thermal power generation and nuclear power generation facilities, greatly reducing the power generation due to thermal power. Exhausted exhaust gas is brought to The harm of human beings, at the same time, can greatly reduce the dangers of nuclear power leakage.

The above embodiments are merely exemplary embodiments of the invention, and are not intended to limit the invention, and the scope of the invention is defined by the claims. A person skilled in the art can make various modifications or equivalents to the invention within the spirit and scope of the invention, and such modifications or equivalents are also considered to be within the scope of the invention.
